摘要： A fixing device includes a heat applying coil formed by winding a wire around the circumference of a coil supporting member disposed along the inside of the cylindrical fixing roller, for heating the fixing roller by inducing an induced current therein, and a pressing roller which forms a nip portion with the fixing roller, and conveys a transfer material gripped by the nip portion between the fixing roller and the pressing roller, thereby fixing a toner image formed on the transfer material by heat energy given from the fixing roller. The heat applying coil is formed by winding a wire so as to have a shape which has parts parallel to the longitudinal direction of the coil supporting member and parts lying along the circumference of the coil supporting member. The winding density of the latter parts is higher than that of the former parts.

摘要： In a toner image fixing device, there are provided an endless belt being looped up around a heating roller and a conveyance roller, a pressure roller for pressing a sheet having a toner image onto the heating roller with the endless belt intervening between the pressure roller and the heating roller. A sensor is disposed inside the loop of the belt so as to come in contact with the heating roller, for detecting the temperature of the heating roller. The fixing temperature for the toner image is controlled on the basis of the temperature of the heating roller detected by the sensor. A first nip region is formed on a pressing portion located between the heating roller and the fixing roller. A second nip region is formed between the belt and the fixing roller, continuing from the first nip region but without contacting the heating roller.
